L., Bortoluzzi, L. C. P., Marques, L. L. M., Formigoni, M., Fuchs, R. H. B., Droval, A. A., & Cardoso, F. A. R. (2020). Medicinal effects of Peruvian maca (Lepidium meyenii): A review. Food & Function, 11(1), 83-92. https://doi.org/10.1039/c9fo02732g. These properties may help in mitigating oxidative stress and enhancing neurotransmitter activity, both of which are crucial for optimal brain function. While more research is needed to fully understand the extent of these benefits, current findings are encouraging for those seeking natural cognitive enhancers.

Benefit 6: Fertility Enhancement

Another significant area of interest is maca’s potential role in enhancing fertility, especially in men. Research has indicated that maca supplementation can improve semen quality, including increases in sperm concentration and motility^[6]Lee, H. W., Lee, M. S., Qu, F., Lee, J.-W., & Kim, E. (2022). Maca (Lepidium meyenii Walp.) on semen quality parameters: A systematic review and meta-analysis. Frontiers in Pharmacology, 13, 934740. https://doi.org/10.3389/fphar.2022.934740. These effects are particularly beneficial for individuals facing fertility challenges. The exact mechanisms through which maca improves fertility are not entirely clear, but they are thought to be linked to its nutrient-rich profile and possible hormone-regulating properties.

Benefit 7: Skin Health

While not as widely recognized as other benefits, maca may also have positive effects on skin health. Some studies suggest that maca can improve skin tone and protect against UV radiation, potentially due to its high levels of vitamins and minerals that are essential for healthy skin^[7]Gonzales-Castañeda, C., Rivera, V., Chirinos, A. L., Evelson, P., & Gonzales, G. F. (2011). Photoprotection against the UVB-induced oxidative stress and epidermal damage in mice using leaves of three different varieties of Lepidium meyenii (maca). International Journal of Dermatology, 50(8), 928-938. https://doi.org/10.1111/j.1365-4632.2010.04793.x. Additionally, the antioxidant properties of maca may contribute to reducing oxidative stress, a factor in skin aging and damage. However, research in this area is still emerging, and more studies are needed to fully establish maca’s role in skin health.
